When running Stella - atari 2800 emulator with OpenGL enabled, I get following error:

Mesa 7.6 implementation error: i915_program_error: Exceeded max instructions

I have also attached Stella's configuration file.

I can take a look but likely the app's shader is just too long for the hardware.
Comment 2 Priit Laes (irc: plaes) 2009-12-24 01:17:15 UTC 
Tried out with mesa-7.7 with gallium backend. Enabling OpenGL caused following crash:

stella: vbo/vbo_exec_draw.c:227: vbo_exec_bind_arrays: Assertion `exec->vtx.bufferobj->Pointer' failed.
Aborted (core dumped)
Comment 3 Eric Anholt 2011-07-13 11:57:22 UTC 
So, I installed stella, ran it, went to video options and selected OpenGL, then restarted the app and it claims it's using GL.  I don't see the error.  Is there more to it to reproduce the failure?

Closing, no updates from reporter, assumable HW limitation. Thanks.
